Specification of Letters Patent.

Patented. May 1, 1906.

Application filed April 5, 1905. Serial No. 254 033.

To a whmn it may concern;

Be it known that I, CLARENCE H. RIGH- WOOD, a citizen of the UnitedStates of America, and a resident of Boston, in the county of Suffolkand State. of Massachusetts, have invented certain new and usefulImprove-'- ments in Vibrator-Applicators and Connections Therefor, offull, clear, and exact description.

This invention relates to that class of device or implement which isemployed as a handpiece, comprises a head in which is mechanism forimparting to the head and the applicator carried thereby rapid,tremulous, pu sating, or vibrating effects beneficially available on theperson for treatment of vari ous conditions, ailments, or diseases, andsomewhat freely referred to as mechanical massaging.

The general description of device to which this invention pertains maybe found in Letters Patent of the United States noticed to be issued tome March 28, 1905, and under No.

786,050. In these devices for subjecting the.

flesh of the person to the Vibratory actions of the applicator theapplicator, which almost of necessityis detachably connected on the headof the vibratory device for interchange as occasion may require, is, byreason of the stemand-socket engagement which it has with the head,liable to become loosened and fall from the vibrator-head or if forcedtoo firmly to its engagement liable to become set, rendering itsdetachment a matter of extreme difiiculty. An object of this inventionis to provide a means of detachable connection between the vibrator-headand applicator whereby the applicator is with certainty tem orarily andduring all times of usage interloclied with the head of the vibrator.

Another object is to constitute in the interlocking device last abovereferred to means whereby a reversal of the motions of the looking partsthereof will result in a positive withdrawal or extraction of theapplicator from any binding or setting which may have been establishedrelatively as between the applicator and the vibrator-head.

Another object is to make provision whereby the vibrator-head may have,either solely or inaddition to an applicator which is axially coincidentwith the length of the vibrator-head and which has its vibrations onsuch axial line to give impacts or blows within which the following is aslight limits, an applicator which as to the axis of its body is atright angles to the line of vibration and as to its working face isparallel with the line of vibration of the head, whereby a rubbing ormore purely massaging effect is possible.

To these ends the invention consists in devices including parts formed,arranged, or combined, and constructed all substantially as hereinafterfully described, and set forth in the claims.

The improved vibrator is illustrated in the accompanying drawings, inwhich Figure '1 is a side View thereof, and Fig. 2 a plan view With endportions thereof in section, each view showing the vibrator as equippedwith two applicators having for each means of detachable rigidconnections. Fig. 3 is a sectional view of substantially the sameapplica tor-connecting device, but showing a modification in theformthereof.

The same or similar parts are designated by similar referencecharacters.

In the drawings, A represents a vibratory device of the character andfor the purpose indicated, the same comprising a cylindrical head B,arranged at right angles to the handle 0, through which lattercompressed air has ingress into the chamber in the head forreciprocating the piston or plunger D to cause a tremulous, pulsating,or vibratory effect, which is transmitted to the applicator orapplicators E and F, which are temporarily rigidly connected to thevibrator-head. The piston or plunger and the walls of the casing withinwhich it has its back-and-forth movements may be any one of severalconstructionsas, for instance, that shown and explained in LettersPatent of the United States granted to me March 28, 1905, N o.786,050and as the present improvements in no way pertain to any meanswhereby the plunger derives its vibratory or reciprocatory movement adescription of any such means is unnecessary. In this class of devicesapplicators of difierent forms and different characters of surfaces areto be interchangeably employed, as demanded in different treatments. Theapplicator shown have the form of disks, although they are sometimes inthe form of bulbs, stems, and otherwise, and are variously made withsmooth surfaces and with protuberances.

The applicator E, which is shown at the i left of the vibrator-head, isextended from such head axially coincident with the longitudinal linethereof and so that when the vibrator device, used as a handpiece andconnected by a flexible conduit with the source of motor-fluid supply,is brought into proximity to the person the latter will receive asuccession of impacts either gentle or comparatively forcible, accordingto predetermination and the adjustment of the vibratorregulating means,as rendered manifest in the aforementioned patent issued to me.Supported rigidly on the vibrator-head and at a position suitablyremoved from the location of the applicator E is the second applicatorF, extending to one side of the vibrator-head and with its axistransverse thereto, whereby the vibratory movement of the head On itslongitudinal line will cause a movement of he applicator F in such amanner that its contacting face ac will rub back and forth on the skindirectly or on any covering therefor.

The hollow cylindrical vibrator-head B is shown as provided with screwengaged endclosing caps G, made with integral bosses b and b the one I)being axially CQincident with the longitudinal center line on thevibrator-head, while the one If is extended at right angles to suchline. Each of said bosses b b is represented as having the externalscrew-threads d and constructed with an endwise opening tapered axialsocket f, and each applicator is made with a centrally-projecting stemor post g, having its extremity tapered, as shown at h, and formed withan external shoulder i, preferably made as a peripheral flange, and forpracticability in construction and assemblage the applicator-head andstem are separably made and permanently united, as made clear in thesection at the left-hand portion of Fig. 2, after the an nular nut J hasbeen interlocked by its internal flange y' with a portion of theapplicatorstem between the shoulder i and the head or applicator proper.It is therefore seen that the applicator carries as a permanentequipment thereof the annular nut having its in-.ternally-screw-threaded portion concentrically surrounding the taperedportion of the stern, and when the nut is brought to screw engagementwith the externally-threaded boss b or b and turned sufliciently theextremity of the stem will be drawn to a tight and rigid binding in thesocket and there retained until wilfully detached.

It being seen that there is, as the parts are specifically shown in Fig.2, a small space between the outer end of the annular nut and the stemside of the applicator, so soon as the loosening movement of the nutbrings its end against the applicator proper a force is imparted toextract or withdraw the stem from its bind, due to the tapering of theparts in the socket.

In Fig. 3 an almost manifest reversal in the same coaction of the Thetapered stem 7%,

arrangement for the parts i represented.

having a shoulder i is here made as the extension or boss of thevibrator-head, while the axial projection b of the applicator isexternally screw-threaded and made with the endwise-opening taperedsocket f and the annular nut having the internal flange or shoulder 9'has the interlocking engagement with the shoulder & and retained forpermanent rotary movements about the part provided to the vibrator-headand for screw-engaging and drawing down the applicator thereto. amtherefore not to be altogether limited as to whether the nut is carriedas a permanent equipment of and by the vibrator -head or the applicator.

I claim- 1. A vibrator-head provided with an external screw-threadedboss formed with an endwise-open inwardly-tapering axial socket, anapplicator having a stern provided with a shoulder and an annular nutscrew-engaging said boss and having an internal projection engaging saidshoulder on the applicatorstem for the purpose set forth.

2. A vibrator-head provided with a boss or pr'ojectionformed with anendwise-opening tapering socket, and provided with screwthreads combinedwith an applicator having a stem to be seated in said tapered socket,and having a shoulder or abutment and an element 'ormed with threads andscrew-engaging said boss or projection and having a part engaging saidshoulder of the applicator-stem, for the purposes set forth.

8. In a device of the character described, a vibrator comprising acylindrical head having an end-closing cap constructed with anexternally-threaded boss or projection having an axial endwise-openingsocket, an applicator having a tapered stem to be seated in said socketand formedwith an external flange and an annular nut screw-engaging saidboss, and formed with an endwise-located internal flange located tosurround said stem between the external flange thereof and theapplicator proper.

4. In a device of the character described, a vibrator comprising acylindrical head having a screw engaging end-closin cap con.- structedwith an integral externa ly-threaded and axially-socketed boss, theaxial line of which is at rig-ht angles to the axis of thevibrator-head, and an applicator pro-. vided with a stem formed taperedand with an external flange and equipped with an annular nut,concentrically surrounding said stern and provided with an internalprojection interlocking between the stem-flange and the applicatorproper and thereby re tained non-detachable relatively thereto.
